Abstract
In 1997, thousands of people gathered in Marrakesh, Morocco, for the first World Water Forum to address an urgent problem: the global water crisis. The meeting resulted in the Marrakech Declaration, a pledge that called on the World Water Council to develop a “World Water Vision” for the 21st century. In 2024, thousands are convening in Bali, Indonesia, for the 10th World Water Forum. Indonesia and Morocco are worlds apart in many ways. As the world’s largest archipelago, Indonesia is surrounded by water. On the other hand, Morocco is partly occupied by the Sahara, the world’s largest hot desert. However, one reality these (and many other) countries share is water stress. The 10th World Water Forum is an invitation to consider the collective water issues in countries as different as Indonesia and Morocco and to draw parallels among them. But it is also about finding solutions This report makes three major contributions. It (1) provides a conceptual framework to illustrate the relationship between water and shared prosperity; (2) presents new empirical evidence on the drivers, extent and costs of inequalities in water access, as well as disparities in the impacts of climate-related water shocks; and (3) identifies policy responses to improve water access, strengthen climate resilience, and promote shared prosperity on a livable planet.

Publication Doing More with Less(World Bank, Washington, DC, 2019-08-28)This report explores how scarce public resources can be used most effectively to achieve universal delivery of water supply and sanitation services. It analyzes the prevalence and performance of subsidies in the sector, then guide policymakers on improving subsidy design and implementation to improve their efficacy and efficiency in attaining their objectives.Publication Can Intense Exposure to Hand-Washing and Hygiene Information Campaigns Affect Children's Socio-Emotional Skills?(World Bank, Washington, DC, 2015-11)Hygiene information and practices play a critical role in preventing diseases, particularly among children. Hygiene behaviors practiced in the household have been linked to development outcomes such as socio-emotional skills. This paper exploits data from impact evaluation surveys of a hygiene information campaign conducted in Senegal, where the randomized design suffered from contamination between comparison groups. The variations in exposure and intensity to hygiene information campaigns captured in the surveys were used to understand contamination biases. Such variations were interacted with the presence of household communication assets to explore potential effects on children’s socio-emotional scores. In the presence of contamination biases, the study exploited the longitudinal sample of children in the surveys to reduce time-dependent biases. For robustness, statistical matching was applied between the impact evaluation surveys and Demographic and Health Surveys conducted in 2008 and 2011. Socio-emotional outcomes were the imputed into Demographic and Health surveys to expand sample sizes. By applying matching techniques and imputing outcomes into a larger sample, impacts were non-negligible. Double-difference estimates showed that children’s socio-emotional scores were higher when intervention status was interacted with the presence of communication assets within households. Without the presence of communication assets in the households the impacts were close to zero. Evaluating the effect of hygiene campaigns on children’s socio-emotional skills is challenging because of the biases from contamination that exist when information flows between comparison groups. Targeted hygiene information to the poorest households is relevant for reducing risks of recurrent infections and enables better conditions for socio-emotional development of children.Publication Overview and Meta-Analysis of Global Water, Sanitation, and Hygiene Impact Evaluations(World Bank, Washington, DC, 2018-05)This paper presents an overview and meta-analysis of the effects of water, sanitation, and hygiene interventions around the world. It is based on 136 impact evaluations (randomized and quasi-experimental studies) that explore the effects of water, sanitation, and hygiene interventions on health and non-health outcomes, ranging from behavior change -- such as the adoption of water treatment -- to school attendance rates, to a reduction in diarrhea. The selected impact evaluations were divided into five groups, and meta-regressions with fixed effects (at the regional level) and random effects were performed, controlling for each study's characteristics (implementing organization, sample sizes, type of publication, number of publication views, and so forth). All results are reported as changes in odds ratios, with respect to the standard deviation of reported effects. Water, sanitation, and hygiene interventions were found to increase the likelihood of behavior changes and the adoption of new hygiene practices by 17 percent. The smallest effects were observed from water, sanitation, and hygiene interventions aimed at reducing the rates of child mortality and non-diarrheal disease. Water, sanitation, and hygiene interventions implemented in schools showed statistically significant results in reducing school absenteeism and dropouts. Similarly, the results showed a statistically significant aggregate likelihood of increased access to safe water and improved water quality, as well as increased water treatment options -- a difference of one-fifth with respect to the standard deviation of the average effect size reported. Finally, the results showed that water, sanitation, and hygiene interventions reduced the likelihood of the incidence of diarrheal and enteric disease by 13 percent, which is consistent with findings in other meta-analyses of the same subject.Publication Increasing the Sustainability of Rural Water Service(World Bank, Washington, DC, 2017-12)evaluation that aims to measure the causal impact of a large-scale rural water supply and services program (PROSASR) in Nicaragua. The overall objective of the evaluation is to assess the causal impact of the provision of technical assistance packages on improvements in the functionality and durability of water systems in rural Nicaraguan communities. Prior to the implementation of the intervention, baseline data were gathered to assess the current levels of functionality and durability of water supply and sanitation (WSS) services, organizational structure and preparedness of WSS system providers, and rural communities and households served by rural water systems. Baseline results suggest that randomized program assignment at the community level resulted in balanced characteristics between treatment and control groups. In a secondary exploratory analysis, community, household, and system indicators were used to identify key determinants of the sustainability of rural water systems. These results will help determine the roadmap for constructing a consistent follow-up survey (2018) to conclude the evaluation and obtain practical policy and program recommendations to improve the program's effectiveness.Publication A Brief Summary of Global WASH Interventions(World Bank, Washington, DC, 2018-05)WASH practitioners and decision-makers lack evidence on the wider health and social effects of WASHinterventions needed to create a paradigm shift in the sector. A global overview and meta-analysis on the effects of different WASH interventions on different health and socioeconomic outcomes was undertaken. The results of this analysis show that evaluations of WASH interventions continue to focus predominantly on reducing diarrheal disease and there is a strong need for larger, more rigorously designed studies covering a broader scope of outcome effects. Similarly, there is a need for greater geographical representation and finally, well-trained implementing agencies to achieve the desired results.

Publication Global Economic Prospects, January 2025(Washington, DC: World Bank, 2025-01-16)Global growth is expected to hold steady at 2.7 percent in 2025-26. However, the global economy appears to be settling at a low growth rate that will be insufficient to foster sustained economic development—with the possibility of further headwinds from heightened policy uncertainty and adverse trade policy shifts, geopolitical tensions, persistent inflation, and climate-related natural disasters. Against this backdrop, emerging market and developing economies are set to enter the second quarter of the twenty-first century with per capita incomes on a trajectory that implies substantially slower catch-up toward advanced-economy living standards than they previously experienced. Without course corrections, most low-income countries are unlikely to graduate to middle-income status by the middle of the century. Policy action at both global and national levels is needed to foster a more favorable external environment, enhance macroeconomic stability, reduce structural constraints, address the effects of climate change, and thus accelerate long-term growth and development.Publication Tanzania Country Climate and Development Report(Washington, DC: World Bank Group, 2024-12-12)The Country Climate and Development Report (CCDR) for Tanzania identifies the impact of climate change on the country’s economy. The CCDR uses macroeconomic, climate, sectoral, institutional, and financial models to identify the economy’s exposure to climate risks and the opportunities to integrate climate action and development. High poverty levels and dependence on rainfed, low-productivity agriculture leaves Tanzania’s economy vulnerable to climate risks. By 2050, climate change could push an additional 2.6 million people in poverty and force up to 13 million Tanzanians to migrate internally. The CCDR presents how implementation of three multisectoral intervention areas could generate climate-positive, resilient, and inclusive growth in Tanzania by 2050. These are: integrating climate considerations when strengthening human capital and social protection; optimizing land and water use and management to boost agriculture and rural productivity, augment climate resilience, and lower greenhouses gas emissions; and prioritizing resilient and low-carbon transport, energy and digital infrastructure systems in urban areas and different sectors. The CCDR details governance arrangements for effective climate change action, presents investment needs, and describes options for mobilizing financing. Action is needed both to reduce vulnerabilities of Tanzania’s current economy and realize the country’s Vision 2050 goal of a more inclusive and sustainable growth trajectory. Targeted climate action could boost private investment and job creation, enabling Tanzania to meet its development objectives in the face of global risks. Technical background reports prepared for the CCDR are available upon request.Publication Poverty, Prosperity, and Planet Report 2024(Washington, DC: World Bank, 2024-10-15)The Poverty, Prosperity, and Planet Report 2024 is the latest edition of the series formerly known as Poverty and Shared Prosperity. The report emphasizes that reducing poverty and increasing shared prosperity must be achieved in ways that do not come at unacceptably high costs to the environment. The current “polycrisis”—where the multiple crises of slow economic growth, increased fragility, climate risks, and heightened uncertainty have come together at the same time—makes national development strategies and international cooperation difficult. Offering the first post-Coronavirus (COVID)-19 pandemic assessment of global progress on this interlinked agenda, the report finds that global poverty reduction has resumed but at a pace slower than before the COVID-19 crisis. Nearly 700 million people worldwide live in extreme poverty with less than US$2.15 per person per day. Progress has essentially plateaued amid lower economic growth and the impacts of COVID-19 and other crises. Today, extreme poverty is concentrated mostly in Sub-Saharan Africa and fragile settings. At a higher standard more typical of upper-middle-income countries—US$6.85 per person per day—almost one-half of the world is living in poverty. The report also provides evidence that the number of countries that have high levels of income inequality has declined considerably during the past two decades, but the pace of improvements in shared prosperity has slowed, and that inequality remains high in Latin America and the Caribbean and Sub-Saharan Africa. Worldwide, people’s incomes today would need to increase fivefold on average to reach a minimum prosperity threshold of US$25 per person per day. Where there has been progress in poverty reduction and shared prosperity, there is evidence of an increasing ability of countries to manage natural hazards, but climate risks are significantly higher in the poorest settings. Nearly one in five people globally is at risk of experiencing welfare losses due to an extreme weather event from which they will struggle to recover. The interconnected issues of climate change and poverty call for a united and inclusive effort from the global community. Development cooperation stakeholders—from governments, nongovernmental organizations, and the private sector to communities and citizens acting locally in every corner of the globe—hold pivotal roles in promoting fair and sustainable transitions. By emphasizing strategies that yield multiple benefits and diligently monitoring and addressing trade-offs, we can strive toward a future that is prosperous, equitable, and resilient.Publication Subnational Business Ready in the European Union 2024: Bulgaria(World Bank, Washington DC, 2024-11-06)This year, the Subnational B-READY series cover 40 cities in six EU Member States—Bulgaria, Croatia, Hungary, Portugal, Romania, and the Slovak Republic—covering 36 European regions. In Bulgaria, the Subnational B-READY covers six cities in six regions at the NUTS2 level: Burgas (Southeastern), Pleven (Northwestern), Plovdiv (Southern Central), Ruse (Northern Central), Sofia (Southwestern), and Varna (Northeastern). The primary objective of the Subnational B-READY studies is to identify and address regional disparities in regulatory environments and to promote reforms that foster private sector growth, job creation, and sustainability. The Subnational B-READY series delivers a rigorous, data-driven analysis of business climates at the local level, offering actionable insights for policy makers.Publication World Bank Annual Report 2024(Washington, DC: World Bank, 2024-10-25)This annual report, which covers the period from July 1, 2023, to June 30, 2024, has been prepared by the Executive Directors of both the International Bank for Reconstruction and Development (IBRD) and the International Development Association (IDA)—collectively known as the World Bank—in accordance with the respective bylaws of the two institutions.
